Let's say that they are giant lecture hall classes with 300 students each. So about 18 sessions per year for 3 hours the first year. 36 sessions the second year.
To teach that load, U of Iowa would need to find 18 instructors at approximately $5-7K a piece in base pay and twice that many in year 2 and beyond. Throw in employer FICA, IPERS, etc and you are likely at over $10K per session.
Plus they would have to find ways to get those into the schedule in those large lecture halls.
But hard to indoctrinate and brain wash (although TBH not that hard to get idiots around here to think Charlie Kirk was a hero) with 300 undergrads who can totally check out during class. So, if you drop it to classes of 100, then you would need 52 sessions year 1 and 104 every year after. That $1 million will not go far.
To think, this was once one of the state's with the best education systems in the country (for over 50 years thanks to be people like Professor Lindquist who pushed the Iowa test of basic skills and created the ACT.
